why do plant cells occasionally switch from noncyclic electron flow (nef) to cyclic electron flow (cef)?
Blizzard [7]

Creating a proton gradient across the thylakoid membrane in higher plants uses cyclic electron flow (CEF), which primarily serves two purposes: (1) producing ATP and balancing the ATP/NADPH energy budget; and (2) defending photosystems I and II from photoinhibition.

ATP and NADPH are produced by noncyclic electron transport. The single product of cyclic electron transport was ATP. Both steps are required by a plant to produce the required amount of ATP for the Calvin Cycle. The electrons are released by photosystem I and then brought back into the system during cyclic photophosphorylation. However, in non-cyclic photophosphorylation, the electrons that the photosystems emit do not come back.

Karen measures the initial volume of water as 12.5 mL. She then adds a 2.3 gram rubber stopper and the volume rises to 20.8 mL.
Archy [21]

Answer:

The volume of the rubber stopper is 8.3 mL.

Explanation:

because the initial volume of the water was 12.5 mL and the new volume was 20.8 mL. So you subtract the 20.8 minus 12.5 and you get 8.3 mL.
